Abstract: The present invention provides a cooling system with supplemental thermal storage. The cooling system comprises a compressor (12), an evaporative condenser (20), a thermal storage unit (40), and an evaporator (80). During normal outdoor temperatures when building cooling is desired, the compressor (12) output is connected to the evaporative condenser (20) which in turn is connected to the evaporator coil (86). During periods of time when the building is not occupied, the evaporator coil (86) is removed from the cooling circuit and the working fluid passing through coils (46) in the thermal storage unit (40) acts to freeze liquid (50) surrounding the coils (46) within the thermal storage unit tank (52). During unusually warm outdoor temperatures, when additional building cooling is required, the compressor (12) output is connected to the evaporative condenser (20) which in turn is connected to the thermal storage unit (40) which output is in turn connected to the evaporative coil (86). During such operation, additionally chilled working fluid is provided to the evaporator coil (86) due to the working fluid passing through the coils (46) of the thermal storage unit (40) and thereby being further chilled due to the frozen liquid (50) surrounding the coils (46) in the thermal storage unit (40).

Abstract: Very low viscosity polymer polyols having high styrene/acrylonitrile ratios and good stability may be achieved by the use of epoxy modified polyols as dispersants. The epoxy modified polyols useful as dispersants may be made by one of three methods: (1) adding the epoxy resin internally to the modified polyol, (2) capping or coupling a polyol not containing an epoxy resin with such a resin, and (3) providing the epoxy resin both internally to the polyol and as a cap or coupler. Epoxy modified polyols having a hydroxyl to epoxy ratio of about 6.8 or less, made by one of these techniques, are superior dispersants and provide polymer polyols having higher styrene contents, and improved stability and viscosity properties. In one aspect, the epoxy modified polyols contain a significant amount of high molecular weight polyol adducts; generally from about 5 to about 30 wt.% of materials having a GPC molecular weight of greater than 100,000; and at least greater than 80,000. Base polyols unmodified with an epoxy resin are used to make the polymer polyols.

Abstract: A universal electronic ballast system (10) is provided for actuating at least one gas discharge lamp (1900) having any one of a plurality of predetermined wattage ratings. Electronic ballast system (10) includes a filter circuit coupled to an AC power mains (100,110) for substantially suppressing spurious signals passing into or from the power source. The filter circuit is coupled to a regulated switching power supply circuit (14) which generates a regulated boost voltage and draws a substantially constant in phase sinusoidal load current from the power source supplied to a switching circuit (16) which generates a regulated pulsating current at a predetermined frequency. Responsive to the regulated pulsating current a high voltage is induced in the primary windings (1710 and 1680) of induction transformer (T3). The high voltage is coupled to gas discharge lamp (1900) by means of the magnetic coupling between primary winding (1730) and secondary winding (1770) of the output transformer (T2). Universal electronic ballast system (10) monitors the presence of gas discharge lamp (1900) by means of the voltage divider (1270,1830) and protection circuit formed by diode (1490), transistors (1380) and transistors (1380 and 1440), for maintaining the switching transistor (1590) in an "off" condition by shunting the base drive signal therefrom responsive to gas discharge lamp (1900) being removed from ballast system (10). <IMAGE>

Abstract: An improved knife clamping system for use in an apparatus for processing wood, such as a flaker, chipper or waferizer, that employs a rotary disc or ring, cutting knives, holding locations mounted on the disc or ring to receive the cutting knives, clamping members to engage and hold the cutting knives in position and fasteners to mount the clamping members to the holding locations. The improvement comprises providing a surface having an undulating profile to engage against the cutting knives. The undulating surface can be formed on the clamping member, at the holding location or at both locations. The surface is shaped to deform to engage the cutting knives with a uniform clamping load upon securing of the fasteners to a pre-selected torque. The foregoing arrangement requires fewer fasteners while still maintaining an adequate clamping force on the cutting knives. This makes parts less expensive and reduces the time to change the knives as there are fewer parts to loosen and tighten.
